Watertight Display ControllerWith the CMS4 Black Box installed, you can control everything from the wired watertight controller. It's simple, robust design maximizes reliability. The vibrant color display allows for simple functionality with enhanced durability that can resist the most harmful of elements. The LCD panel is optically bonded to hardened glass for superior scratch and fog resistance, clarity, and glare reduction.

Intuitive Multi-Zone InterfaceClarion's unique multi-zone interface makes controlling different regions of your vessel a breeze. From one screen you can see what source is being played in each zone and even link the ones you want to control simultaneously.

4-Zone ControlSince you can control up to 4 independent zones on the same vessel, people can enjoy listening to different sources in the cabin, in the cockpit, and on the deck. For example, relax to soothing background music in the cabin, get the party rolling on deck with some upbeat tunes, and keep your ears on the weather in the cockpit. Every space and every situation gets its own soundtrack.

4-Zone Volume ScreenIntegrated multi-zone volume screen instantly shows you what volume each zone of your vessel is currently set to. The intuitive readout also quickly shows you which zones are linked and even allows you to override a specific zone's volume with a quick turn of the volume knob.

Dedicated Remotes for each of the Four Available ZonesThe CMS4 has 4 discrete wired remote ports that allow each zone to be controlled by its own set of remotes. This allows your passengers to control their zone from a remote that is installed in a convenient location.

Day/Night ThemesHigh-contrast day theme makes viewing information on the CMS4's display controller screen effortless, even in bright sunlight. Night theme alters the colors so that piloting the vessel when the sun goes down won't stop your entertainment. Day and night modes can be automatically triggered via the unit's dimmer wire or manually in the setting menu.
